How much did your kid’s car insurance cost you?

Parents know that insuring a teenage driver is costly, and the website insuranceQuotes.com has figured how much: A couple’s premium goes up nearly 80 percent when they add a teenage driver to their policy.

In a state-by-state breadown, Missouri, at an 80.5 percent increase, and Kansas, at 79.1 percent, are right in line with the country.

Nationally, adding a teenage male causes a 94 percent increase; it’s 67 percent for a teenage female. The biggest spike, 96 percent, comes for 16-year-olds. That drops to 60 percent for 19-year-olds.

The average hit is biggest in New Hampshire, at 115 percent, followed by Wyoming, 104 percent; Illinois, 104 percent; Maine, 103 percent; and Rhode Island, 102 percent.

Only Hawaii, at 17 percent, had an average increase below 50 percent. It’s the only state that doesn’t let insurers figure age and driving experience into their rates.

The costs were figured by surveying the largest insurers in each state, and based on the couple each being 45, having good credit and driving records, driving 12,000 miles a year, and with policy limits of $100,000 for injury liability for one person, $300,000 for all injuries and a $500 deductible on collision and comprehensive coverage.

InsuranceQuotes.com says costs have come down a bit since 2013, when the average annual increase for adding a teen was 85 percent.
